RCD - Autoresetting

So the device in the first link counts 3600 cycles of the 60 Hz and then tests. Probably gives a marginal increase in reliability vs. checking once/month.
Not a bad idea.

Electronics-wise this should probably add $1 or less to the cost of each GFCI, assuming the manufacturer is buying in huge lots. They have to add a 12 (16 for the second link) stage binary counter IC to the PC board.

Thanks for the replies.

I am located in Australia - RCD are compulsory over here. In my situation, the RCD gets triggerred occassionaly and when I visit the holiday home where its installed - the fish in the aquarium are dead and the frig is full of mould etc
The devices seem to be popular and widely used in Europe and UK from what I can gather.

You seem to want a device that decides if it tripped for a valid or invalid reason.
For houses this decision is usually made by a human with test equipment, although I think power companies have automatic reclosing circuit breakers that try several times to energize a circuit that initially caused an overload, in the hope that the fault has since cleared.

If no one makes such a device, you could make it yourself by modifying a GFCI but the details of that project are somewhat beyond the scope of this forum.
You could try electro-tech online but I'm not sure making such a device would be wise for an unoccupied house.

So you need a GFCI that waits this interval of seconds, minutes or hours and then retries for a few times.
A GFCI, relay & timer will do it. If you can post the schematic of a candidate GFCI I may be able to step you through it.

Which verison you want ?

There is a breaker and power point verison.

However the powerpoint verison is not super common but we can get it from time to time.

And what brand Customer panel or breaker panel you have there so I can able look it up.

Quoting a data sheet for an IC!?!?!? You probably can't even buy the part in less that 100k piece lots. Hardly a helpful suggestion. Also what about UL and related safety approvals. That is probably a $50-75k fee for submittal.
